Best fuel economy is in the right foot and minimizing drag. Closed sunroof, minimal use of a/c etc. Holes in hood hurt resale value, but each to his/her own
yes holes hurt resale value, but in the moment they work. Nothing a little piece of aluminum behind the hole, body filler and fresh paint won't hurt. As you can see, the hood is pretty beat up paint wise, so bondo and fresh paint and she's as good as new.
As far as doing it stock... I would say out of convenience that Mazda didn't do this cause im sure the average owner didn't want to have to have some sort of button, or block off plate to install when it rained, or having it go through a car wash, or washing it your self. Its not pretty, but im sure i'll have another way to make it look a little nicer. This is only the first design... a second one will come thats more visually appealing, or is incorporated so that some sort of cap can just slide or be screwed on to the scoop.
